Colossians 3:17 reads, in the King James, "And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by Him." Certain parts are a little more stressed I think in the Amplified version which reads, "and whatever you do [no matter what it is] in word or deed, do everything in the name of the Lord Jesus and in [dependence upon] His Person, giving praise to God the Father through Him."
Whatever you do, do everything to the best of your ability and then thank God for the ability to do whatever it is you are doing. This can be one example of how you can be a fisher of man. Be the best example you can be for Christ.
